 Posted: Sun Jun 23, 2024 8:54 pm Post subject: ZFS system: grub-mkconfig is misidentifying my root dataset |
 |
|
I loosely followed Ali3nx's Installing Gentoo Linux EFISTUB On ZFS during a storage upgrade on my main home server and have had a working ZFS root "partition" since around Christmas. The vital statistics of my zpool and datasets are: | Code: | ceres ~ # zpool status
pool: rpool
state: ONLINE
scan: scrub repaired 0B in 02:14:12 with 0 errors on Wed Apr 24 10:45:01 2024
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
raidz2-0 ONLINE 0 0 0
scsi-2b1ea01f100d00000-part4 ONLINE 0 0 0
scsi-2b1ea513300d00000-part4 ONLINE 0 0 0
scsi-2b1eaa12700d00000-part4 ONLINE 0 0 0
scsi-2b1fa01e700d00000-part4 ONLINE 0 0 0
errors: No known data errors
ceres ~ # zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 1.20T 12.7T 140K none
rpool/ROOT 1.18T 12.7T 140K none
rpool/ROOT/gentoo 1.18T 12.7T 1.18T none
rpool/home 27.0G 12.7T 140K none
rpool/home/jgraham 27.0G 12.7T 27.0G none
rpool/usr 140K 12.7T 140K none
rpool/var 279K 12.7T 140K none
rpool/var/lib 140K 12.7T 140K none
ceres ~ # mount | grep 'on / '
rpool/ROOT/gentoo on / type zfs (rw,relatime,xattr,posixacl,casesensitive) |
The issue I'm having is that grub-mkconfig has begun to misbehave. The correct kernel command line parameter to mount my root dataset would beroot=ZFS=rpool/ROOT/gentoo but what grub-mkconfig is coming up with isHas anyone else seen this issue? And, yes, I know I could plug the right parameter into GRUB_CMDLINE_LINUX in /etc/default/grub, whcih is what I've just done, but I'd prefer a solution over a Band-Aid. I'm about to research upstream bugs & then perhaps file one.
The usual demographic data are:- It's a genkernel "kitchen sink" kernel. Config file shouldn't matter, but it's here.
- /etc/genkernel.conf is here.
- emerge --info is here.
- /etc/default/grub is here.
- And grub is built with these USE flags.
(I'm also mad at myself because I first encountered this sometime in the spring and apparently manually patched /boot/grub/grub.cfg and went on about my business—and forgot about the whole thing—so, the next time I upgraded my kernel, well, you know.)
Thanks in advance for the help.
- John

Looks like that bug was being shepherded by Cardoe, but died on the vine due to lack of timely response to questions from upstream, perhaps due to his Gentoo retirement. I'm going to try to pick this up.
There's an ebuild up on my JRG overlay that contains a provisional fix.
